The players have an incredible knack for finding the most incredible and unimaginable glitches in a great majority of games, even if there has been extensive testing, there are no games that are glitch free.
Not really, its the people who use the perk. When people use the perk to just spam nade then it gets annoying, but when people use the perk strategicly then I don't mind it. I do pull off some amazing nade shots cooking + through windows etc. It's always fun ^^ I loved cooking nades on cod4.
